The influence of zero-tillage practice on soil, weed control during winter fallow and growth behaviour of sorghum and cotton is discussed in relation to conventional practice. In a year of partial drought when all yields were reduced, zero-tillage gave slightly superior results, but when moisture was adequate it depressed yields by up to 40%. The yields of following crops of wheat and vetch after sorghum, were depressed in the zero-tillage plots by 5-30% in 2 field experiments, compared with conventional practice. CCT.

In a brief review, earlier German and English attitudes to tillage research are contrasted, especially on the emphasis on soil structure v emphasis on weed control; the effect of the advent of zero tillage on this difference is discussed. It was concluded that chemical weed control gives greater freedom in tillage practice, and research is revealing risks that may be unacceptable for certain crops when tillage practices are changed.

A field experiment was conducted to evaluate the plant height, yield and yield attributes of wheat under different tillage practices and nitrogen level at Dang, Nepal during winter season 2018-19. The experiment was laid out in split plot design with two tillage practices viz. zero tillage and conventional tillage as main plot factor and four level of N viz. 50 kg ha-1, 75 kg ha-1, 100 kg ha-1and 125 kg ha-1 as sub plot factor and each replicated thrice.  The result revealed that there is no significant relation between tillage practice and plant height of wheat while N level significantly affect the plant height. 125 kg N ha-1 recorded the highest plant height (110.7 cm). Zero tillage recorded the highest effective tiller m-2 (254) and grain yield (3.3 t ha-1) whereas spike length, grain spike-1, biological yield and harvest index were not significant with tillage practices. Regarding the N level, 125 kg N ha-1 recorded the highest effective spike m-2 (279), spike length (10.6 cm), grain spike-1 (48), thousand grain weight (46.3 g), grain yield (3.6 t ha-1) and biological yield (9.4 t ha-1). 50 kg N ha-1 recorded the highest harvest index (42.9%). The interaction between the tillage practice and nitrogen level showed the significant effect on grain yield and harvest index where as other parameters showed non-significant relation. The zero tillage with 125 kg N ha-1 recorded the highest grain yield (3.9 t ha-1).

The effects of tillage practice and double cropping on growth, yield and N economies of summer crops were examined in field experiments near Tamworth, northern New South Wales. Sorghum, sunflower, soybean, mungbean, cowpea and pigeon pea were sown into alkaline, black earth soils which contained either high (Site A, sown January 1983), moderate (Site B, sown December 1983), or low concentrations of nitrate (Site C, sown December 1984). During the previous winters, the land had been sown to wheat (double crop) or fallowed using cultivation or no-tillage practices. At Sites A and B, dry matter yields, averaged over all crops, were increased by 34 and 14% under no-tillage. Average increases in grain yields at the two sites were 22 and 11%. At Site C, tillage practice did not affect yields. Soybean showed the greatest responses to no-tillage. Increases in grain yields were 46, 15 and 18% for Sites A, B and C respectively. The least responsive legume was mungbean. Yields of sorghum were increased by 41% at Site A; responses at Sites B and C ranged between a 9% decrease and a 7% increase. With double cropping, grain yields were, on average, 18 (Site A), 81 (Site B) and 72% (Site C) of the yields in the cultivated (fallow) plots. However, when comparisons were made for the 12 month periods, i.e. wheat and summer crops v. fallow and summer crops, production was more than doubled at Site B and tripled at Site C, compared with the cultivated fallow. Significant in the responses to double cropping were the 192 (Site B) and 230 mm rainfalls (Site C) during November and December that replenished the soil profile with water to a depth of >0.75 m. Assessments of soybean N2 fixation using the ureide method indicated large effects of site and season on the proportion of plant N derived from N2 fixation (range, 0-0.83), on the amount of N2 fixed (range, 0-233 kg N ha-1) and on the N balance as a result of the cropping (range, -69 to +45 kg N ha-1).

The aim of this investigation was to estimate the effects of foliar fertilization on quantitative traits (plant height, first pod height, number of nodes per plant, number of pods per plant, number of grain per plant, grain yield per plant, 1000-grain weight and grain yield) in two soybean cultivars (Balkan and Becejka). Studied cultivars belong to different maturity groups (Balkan - I and Becejka - 0). Four treatments of fertilization were tested: control (no fertilization), Urea (46 kg N ha-1), Urea (46 kg N ha-1) + Wuxal super (5 l ha-1) and Urea (46 kg N ha-1) + Ferticare I (5 kg ha-1). Wuxal super and Ferticare I were foliar applied two times at the R2-R3 growth stage. The field experiments were carried out in dry land farming in the region of Vojvodina province at location Putinci (45? 00? N Lat., 19? 58? E Long.), during the years 2007 and 2008. In both research years, Balkan had higher values for all investigated traits than Becejka. Results showed that foliar fertilizers significantly increased the values for all quantitative traits. Ferticare I is more effective than Wuxal super in soybean because this fertilizer has higher concentration of macronutrients. Foliar fertilization of soybean reduced the negative impact of small amounts of rainfall during the summer months on grain yield.

Field experiments were conducted to determine the effect of mature crop residues and volunteer seedling residues of canola (Brassica napus L.), barley (Hordeum vulgare L.) and flax (Linum usitatissimum L.) on the growth and yield of subsequent flax crops seeded after conventional tillage. A second set of field experiments was also conducted which included both flax and barley as test crops on canola and barley stubble and included an additional comparison between conventional tillage and no tillage. Flax yields were generally lower on canola and flax stubble than on barley stubble with conventional tillage before seeding. Averaged over 6 yr the reduction was 9% on canola stubble. With no tillage prior to seeding, flax yielded as well on canola as on barley stubble. Spring volunteer seedlings of canola and flax often reduced flax yields but fall volunteer growth had no marked effect. Barley yielded better on canola than on its own stubble, and tended to yield better with tillage prior to seeding than without.Key words: Flax, Linum usitatissimum L., crop residues, phytotoxins, tillage practices

Over the years, cultivation using sustainable tillage practices has gained significant importance, but the impact of tillage on soil water infiltration is still a concern for landowners due to the possible effects on crop yield. This study investigates the impact of different tillage managements on the infiltration rate of sandy clay loam soil under a semiarid environment. Field experiments were conducted in Chott Mariem Sousse, Tunisia. The tillage practices consisted of three treatments, including a tine cultivator (TC, 16 cm), moldboard plows (MP, 36 cm) and no-tillage (NT). Three infiltration models, Kostiakov, Philip and Horton, were applied to adjust the observed data and evaluate the infiltration characteristics of the studied soils. Comparison criteria, including the coefficient of determination (R2), along with the root mean square error (RMSE) and mean absolute error (MAE), were used to investigate the best-fit model. The results showed that moldboard plowing enhanced soil infiltration capacity relative to tine cultivation and no-tillage treatments. The mean saturated hydraulic conductivity was highest under MP, while it was lowest in NT, with 33.4% and 34.1% reduction compared to TC and MP, respectively. Based on the obtained results, Philip’s model showed better results with observed infiltration due to a higher R2 (0.981, 0.973 and 0.967), lower RMSE (3.36, 9.04 and 9.21) and lower MAE (1.46, 3.53 and 3.72) recorded, respectively, for NT, MP and TC. Horton’s model had a low regression coefficient between observed and predicted values. It was suggested that the Philip two-term model can adequately describe the infiltration process in the study area.

Field experiments are described comparing a wide range of annual, winter-growing legume species with regard to their grain yield and protein content in South Australia. In 1974, a year when rainfall was considerably above average, Vicia faba (fieldbeans) outyielded all other species at each of two sites, eighty lines producing a mean yield of 8.2 t ha-1 of air-dry grain. In 1975, when rainfall was again generally above average but poorly distributed, V. faba, V. sativa and certain Lathyrus species yielded well, while other crops maintained average yields or failed in specific environments. The relative merits of new crop species in the diversification of rotations in dry land farming are discussed and it is concluded that field beans could be developed rapidly into a valuable alternative grain crop.

Two field experiments were conducted in central Iowa to assess the effects of tillage on Heterodera glycines dissemination and reproduction and soybean (Glycine max) yield. Plots in both experiments were artificially infested with equivalent numbers of H. glycines cysts. In one experiment, plots were left noninfested or received aggregated or uniform infestation, and a susceptible soybean cultivar was grown for 3 years. By the end of the first growing season and through the second, H. glycines population densities were consistently greater (P ≤ 0.05) in uniformly infested plots than in plots with aggregated infestations. No differences in soybean yield among the treatments were detected. In a second experiment, a 1-m2 area of each plot was infested with H. glycines cysts, susceptible soybeans were grown for four seasons, and crop residue was managed with either ridge-, conventional-, reduced-, or no-tillage. After 1 year, nematode population densities were significantly (P ≤ 0.05) greater in conventional- and reduced-tillage treatments than in no- and ridge-tillage treatments. After 2 years, H. glycines had been disseminated 6.9 m from the infestation site in conventional- and reduced-tillage treatments but only 0.5 and 1.4 m for no-tillage and ridge-tillage treatments, respectively. After 3 years, H. glycines population densities were 10 times greater in conventional- and reduced-tillage treatments than in the no-tillage treatment; conventional-tillage was the only treatment with yield significantly lower (P ≤ 0.05) than the noninfested control. Aggregation of H. glycines eggs was greater (P ≤ 0.05) in no- and ridge-tillage treatments than in conventional- and reduced-tillage treatments. Results indicate tillage can quickly disseminate H. glycines in newly infested fields, facilitating more rapid nematode reproduction and subsequent yield loss.

The present experiment was conducted to evaluate two important conservation tillage practices namely zero tillage in wheat and bed planting for growing vegetables for deciding the economic feasibility of their adoption in Gohana and Kharkhoda block of Sonipat district in Haryana. In first scenario, comparison were made between Puddled transplanted rice followed by conventional tilled wheat (PTR – CTW), and puddled transplanted rice followed by zero till wheat (PTR – ZTW). In second scenario, conventionally tilled Jowar in kharif followed by conventionally tilled wheat system (CTJ – CTW) was compared with vegetables on beds in both seasons (BV-BV). Sowing of wheat by zero till drill in PTR – ZTW system, decreased cost of cultivation by 21% over its value of Rs 20688 in PTR – CTW treatment; increased grain yield by 5% over the grain yield of 5.99 t ha-1 in PTR – CTW treatment. The B: C ratio of PTR – ZTW was 4.65 while that of PTR – CTW treatment was 3.24, which indicated economic viability of zero tillage practice. While in case of cauliflower in BV-BV system, the total cost of cultivation was estimated at Rs 51500/ha and net returns of Rs 38072/ha i.e an increased net return of 5.8 times over the net return of Rs 46223.5 in CTJ – CTW treatment. The B: C ratio of BV-BV was 5.21, while that of CTJ – CTW treatment was 2.35. Thus, it was concluded that in rabi season, cauliflower on beds and zero till wheat are most economically viable options in this temporary waterlogged regions of Yamuna basin.
